  • In this study, we investigated the characteristics of the PCK components in the chemistry units of middle school science teacher's guidebooks developed under the 2009 Revised National Curriculum. The analysis of the results revealed that the sub-components of topic-specific strategies, vertical articulation, and lesson objectives were systematically handled in most teacher's guidebooks. However, subject-specific strategies, assessment methods, and curricular changes were mainly dealt with only in the general guidelines. Experiments and inquiries, assessment questions, and assessment dimensions were lack of constructivist approaches in the aspect of presented contents or forms. Horizontal articulation and knowledge of students were either lacked in relevant content or presented in the form of simple presentation. Concepts and theories accounted for the largest proportion of teachers' guidebooks, but some of them were beyond appropriate levels. On the bases of the results, the implications for the development of the teacher's guidebooks are discussed.

  • Majority of knowledge management(KM) studies in e-government have been confined to facilitate KM within an organization. But due to citizen-centric(citizen-driven) paradigm shift and advance of web 2.0 communication in recent years, KM between governments and citizen in e-government portals is becoming an important consideration. So a series of studies on knowledge enhanced e-government portal get under way by considering that it is necessary to enhance knowledge of e-government portal and assuming it improves the usability of portal. While the topics of knowledge enhancement and e-government(portal) are widely discussed in their own domains there is a paucity of studies that address these constructs in a joint context. This paper aims to propose conceptual framework of knowledge enhanced e-government portal through structuralization of theoretical discussion with holistic approach. This framework presents an evolutional path of knowledge enhanced e-government portal that consists of three phases and it will be used for realizing the knowledge enhanced portal project as a basic reference model.

  • Picture books, as a genre, are characterized by conveyance of ideas through linguistic texts, visual texts, and the complementary interactions between them. The writer of a picture book develops and delivers his or her ideas with textual contents written in a unique style, while the artist conveys the writer's ideas through pictures where things, objects, and figures are imbued with various emotions. Understanding a picture in a picture book requires an understanding of both the structure shown on the surface and the underlying structure that adapts and visualizes the philosophy and ideas of the writer. In light of the discussion above, this study proposes a method to help librarians improve their understanding of visual literacy for picture books, as visual literacy is required for the provision of readers' advisory services regarding picture books. This method, which is based on behavioral psychologist Rudolf Arnheim's theory of visual thinking, is expected to help librarians write picture book reviews or other secondary materials.

  • Business is the key component of a capitalist system, and, recently, archives management in businesses has been emphasized to secure the transparency of business administration. However, until now, almost 20 years since archival studies were introduced in South Korea, there is a noticeably low interest in archives management. Archival studies in academic circles are still insufficient, and the level of archives management in the field of business practices is very low. For example, no academic discussions have been conducted on the concept and characteristics of business archives, as well as the suitability of the use of such terms. Thus, this study aims to prepare the basic foothold of business archives management studies in the future, examining the concept of "business archives." For this purpose, this study would diagnose the present situations and help readers understand theoretical discussions by introducing actual cases of business archives management.

  • This study is to investigate the theoretical background of the content system for an integrated approach to multi-cultural education. It has been expanding to children from general family even though started to support children from multi-cultural family. Most of multi-cultural education programs would be their purpose as building the multi-cultural citizenship even though various multi-cultural education have been introduced. These programs had limited to apply western multi cultural education into Korea school, and Their focuses were not who is person to be morally educated in the multi cultural society. Thus, this study put emphasis on the necessity of and developed the content system for an integrated approach to multi-cultural education.

  • Since there are differences in the content, structure and functions of interpersonal communication during the practice of school science classes, it needs to articulate the difference of the modality of pedagogical practice in order to understand science teaching in detail. These characteristics of science teaching can be investigated by further insightful analysis on language in the science classroom. In this study, classroom discourse language codes using Bernstein's code theory were analyzed in the case of a middle school science class on the unit of minerals. The discourse language code was identified by the value of classification, which revealed power relations to the contexts of discourse and participants of discourse. It was also identified by the value of framing, which showed hierarchical relation between teacher and students as discourse subjects, and discursive control on the initiative of discourse. The results addressed that six types of discourse language codes were constructed and that those language codes reflected diverse modalities of science teaching from student-centered instruction to teacher-centered instruction in relation to classroom discourse. The modality of science teaching according to the transition tendencies of discourse language code showed dynamic variations of 'controlled student-centeredness inducing teaching' - 'positional student-centeredness permissive teaching' - 'controlled students' participation permissive teaching' - 'controlled student-centeredness facilitative teaching' - 'student-centeredness enhancing teaching'. In addition, results released that discursively and hierarchically weak control of discourse is necessary for enhancing student-centeredness of science teaching. Moreover, teaching practice enhancing student-centeredness can be accomplished by the harmony of a teacher's perception of discourse language code and his/her orientation to constructivist teaching and student-centered teaching.

  • The study attempted to articulate standpoints towards compulsory education system based on schooling age and year in careful considerations with the gifted. For these ends, literatures were reviewed and various education laws, regulations and documents and related law reports and judicial decisions were investigated. Literature review was conducted to develop that ideas of rights to compulsory education for regular students are closely related to those for gifted. Structures of general education laws and gifted education law and regulations were compared. Later, limitations of compulsory education were discussed when it was applied for the gifted. In conclusions, it is inappropriate that the gifted are ruled by compulsory education system based on schooling age. If compulsory education system is designated to provide an effective opportunity for all students, it should be duties and rights to enter elementary schools at schooling age. However, it appeared that the duties and rights to enter elementary schools at certain schooling ages function as inhibitors against the gifted with giftedness and potentials far beyond those of regular students. Therefore, the gifted should be separately ruled under flexible systems of compulsory education if their achievement level is assessed as sufficient to enter elementary schools before schooling age. On the other hand, legal systems of compulsory education are gradually evolved to flexible systems. However, it is necessary to establish social atmosphere and support system of educational administration in order to practice the flexible system of compulsory education for the gifted.

  • Sciences and technologies are the sources which have formed presently highly developed civilizations and cultures and have enhanced the quality of human lives. But we see the dark sides of them as well as the bright sides, and we have the consciousness of environmental crisis and destruction of lives caused by them. Thus were are criticisms against human-tropism or technology-tropism from nature-tropism or deep ecology. However, if people would continue to have the desire of enjoying the present quality of their lives, they should try to develop and improve pro-environmental technologies. In this vein, we have the necessity of making environmental decisions and solving environmental problems by information technologies. Since the second half of the last century, 'environment' is the key word because we have the consciousness of environment strongly. As we solve human problems by making decisions of actions, we must face with environmental decisions in order to solve our environmental problems. If we have the better understanding of the nature of information and the role of information technology, and the relation of information technology and decision-making, we are able to design environmental systems and implement their optimal interfaces of environmental components. For this purpose, we are obliged to combine several useful technologies including GIS, DSS, Knowledge-based system and artificial neural networks. Therefore the developments and cooperations of these fields in environmental decision making enables us to live in the better and comfortable surrounding in the near future.

  • 효율적 물관리란 거대한 물순환 과정에서 인간이 편안한 삶을 사는데 필요한 물의 이용효율을 극대화하는 것이다. 과거의 물관리는 이원화된 수량과 수질관리, 수량중심에서는 용수공급과 홍수조절이 주요한 관심사였다. 현재는 과거의 물관리에 친수와 환경을 더한 복잡한 분야로 확대되고 있다. 통합물관리란 물을 최적으로 관리하기 위해 물관리 이해당사자간의 소통과 물 기술의 고도화를 기반으로 기존에 분산된 물관리 구성요소들(시설 정보, 수량 수질 등)을 권역적으로 관리하는 것을 말한다. 본 연구에서는 대청댐 방류에 따른 금강 하류부의 홍수추적을 위해 수행한 댐하류 소유역별 강우량 빈도분석 과정, 용담댐 방류를 고려한 대청댐 홍수도달시간 검토, Poincare Section과 신경망기법을 이용한 수문자료 예측, 추계학적 다변량 해석과 다변량 신경망해석에 의한 대청댐 유입량 산정과정, 보조여수로 건설에 따른 주여수로와 보조여수로간의 연계운영방안, 단계(관심, 주의, 경계, 심각)를 고려한 대청댐 확보수위 산정, 저수지 중장기 운영계획 수립과 댐 운영 기준수위를 결정하기 위해 누가차분방식으로 적용되는 갈수기 유입량 빈도분석에 대한 실무적용 사례를 소개하고자 한다. 강우량 빈도분석 과정은 L-모멘트방법(Hosking과 Wallis, 1993)을 적용하였고, 홍수도달시간 검토는 평균유속, 하류 수위상승 기점 영향검토, 수리학적 모형(FLDWAV, Progressive lag method 등)을 활용하였다. 카오스 이론을 도입하여 대청댐 수문자료의 상관성 검토 및 추계학적 모형을 이용한 모의발생을 유도하여 수문자료 예측을 시행하였다. 추계학적 모형과 신경망모형 연구의 대상은 대청댐으로, 시계열 자료는 댐의 월강우량, 월유입량, 최고기온, 평균기온, 최소기온, 습도, 증발량 등의 자료를 기반으로 하였다. 적용기간은 1981~2009년의 자료를 이용하여 2010년 1월부터 12월까지 12개월 동안의 월유입량을 예측하였다. 수문자료 해석의 기본이 되는 약 30년간의 자료를 이용하여 분석을 실시하였다. 대청댐의 유입량 예측을 위해 적용된 모형으로는 추계학적 모형인 ARMA모형, TF모형, TFN 모형 등이 적용되었고, 또한 신경망 모형의 종류인 다층 퍼셉트론, PCA모형 등을 활용하여 실측치와 가장 가깝게 근사화시키는 방법론을 찾고자 하였다. 또한, 기존여수로와 보조여수로 연계운영을 위해 3차원 수치해석을 통한 댐하류 안정성 검토 및 확보수위 산정을 통해 단계(관심, 주의, 경계, 심각)별로 대처가 가능한 수위를 산정하였다.

  • It is well known that personality and situation which person possess have an impact on the relationships between stress coping and psychological wellbeing. Although most of studies on cultural self-construal have used the concept of individual/collectivism (independent/interdependent) scale, a part of research showed that it was not similar results when the concepts were used with Korean samples. We applied new scale, subjective-objective self, to our study. Two hundred eighty three participants (M = 21.66) participated in the present research. We found that persons with higher subjective self used more problem solving and seeking help, and less denial coping methods. Next, the higher subjective self influenced happiness and interpersonal relationship satisfaction. Finally, the coping methods of problem solving and seeking help influenced more happiness and interpersonal relationship satisfaction among people with higher objective self than did among people with higher subjective self. The implication for study were discussed.
